To all whom it may concern:

Be it known that I, LADISLAV VOJACEK, a resident of Prague, in theKingdom of Bohemia, Austria-Hungary, have invented certain new anduseful Improvements in Rotary-Disk Motors, of which the following is aspecification.

My invention includes a pair of disks arranged with a small spacebetween their peripheries adapted to receive a steam, water, or otherjet directed to the point of meeting between the wheels, said jet actingby its force and adhesion upon the adjacent part of the wheels or disksto rotate the disks. The jet as used by me acts upon the disks in amanner similar to a rope moving in contact with the disks and passingthrough the small passage between their peripheries.

In the drawings, Figure 1 is a side view of one form of. my invention,and Fig. 2 a plan view of the same. Figs. 3 and 4 are similar views ofdisks with modifiedf orms of peripheries. Figs. 5 and 6 are furthermodifications of the disk rim and the nozzles adapted thereto. Figs. 7and 8 are plan views of further modifications, and Figs. 9, 10, 11, and12 show side elevations and plans of other modified forms of disks. Fig.13 is a side view of a ring form of motor, partly broken away. Fig. 14is a central vertical section of the same. Figs. 15 and 16 represent inelevation and plan, partly in section, a modified-arrangement of parts.Fig. 17 is a diagrammatic view showing a second pair of Wheels with ajet arranged to receive the fluid from the first jet. Fig. 18 is adetail sectional view. Fig. 19 is a side view, partly in section, of amechanical connection between the disks to keep them at the same speed.Fig. 20 is a plan, and Fig. 21 a detail, of the same. Figs. 22 and 23show disks with a plurality of jet-nozzles. Figs. 24, 25, 26, and 27 aredetails of modifications. Fig. 28 is a plan view of a series of disks.

A B, Figs. 1 and 2, show two rotary disks on shafts a, and b and c thejet of steam or other fluid being directed to the meeting point of theperipheries of the disks. If the space between the disks is alittle lessin cross-section than the cross-section of the jet, the disks will berevolved by the jet simply by the adhesion of the material forming thejet, which having a larger cross-section than the space between thewheels will act like a rope or band, which would be forced through thespace. If the space is circular in cross-section, as at m, in Fig. 2,the central part of the body of fluid forming the jet will escapethrough the opening without effect. To avoid loss of this kind, I insome cases form one disk with an edge, as shown at t, Figs. 4:, 5, and6, and the other disk has a groove fitted to receive the rib or edge if.The jet is divided by this edge and spreads out on each side, escapingthrough the small V-shaped space between the corresponding surfaces ofthe disks. This will materially increase the adhesive effect of the jet,which, as it spreads over the divergent surfaces, will exert its fullforce on the disk. The jet-nozzle C, as in Fig. 6, may be divided todirect a jet onto each of the inclined surfaces on each side of the edgeif.

In Fig. 7 a plurality of rills or grooves and corresponding ribs areshown at t 15 Fig. 8 shows a series of grooves 7, 8, 9, and 10, formedin the V-shaped small space between the disks.

Figs. 11 and 12 show a plurality of ribs, such as shown in Fig. 2, thegrooves corresponding to m, being shown at 1, 2, and 3.

Figs. 9 and 10 show two disks, in which the small space between them isprovided by a flat rib on one disk entering a similar groove in theother wheel.

In Figs. 13 and 14: a ring-shaped disk A is used, disk B being within itand fitted to the V-shaped groove thereof. A jet from nozzle 0 isdirected to the pointof contact between the disks. A third disk 13 hasan outside contact with the ring disk, which has on its peripherypockets q to receive thejet from a nozzle 0 This shows the combinationof my invention with a bucket-form. of disk. The shafts b b of the disksB B are supported in bearings on the framework '0 v pivoted at a a andadjustable by the screws W W to adjust the disks B B to or from the ringdisk.

Figs. 15 and 16 show a disk B, having a flat rib, and a disk A, having acorresponding groove, the small space between them at the point ofcontactbeing shown at n. The disk .ais the motor-disk in this form, theother disk B having no other object excepting that of confining the jetso as to produce the adhesion. The jet comes from a nozzle 0, having aflattened end to make a broad jet. Suitable means of adjusting thejet-nozzle are shown at S. The casing L collects water of condensation,the jet in this case being a steam-jet. H is an outlet-pipe for thespent fluid of the jet. If the jet after passing through the disks A Bhas still considerable force, a second nozzle 0' may be used, Fig. 17,to force the jet to a second pair of disks. The two disks may bearranged to revolve at the same speed by making a positive contactbetween their peripheries, as shown in Fig. 18 at p, in which case thedisks will revolve by friction. In this case the small jet-opening isshown at at, through which the fluid is forced to get the adhesive orrope-like effect. By thus causing the disks to revolve at equal speedsthere is no internal friction between the particles of the jet itself,as would be the case were the jet on one side of its center to beretarded, while on the other side it would have a higher speed or flow,thus breaking up the jet within itself. The same result may be obtained,as in Figs. 19, 20, and 21, by providing the shafts a b of the disks A Bwith worms 7& 10 meshing with worm wheels K K on the common shaftf, fromwhich the power is transmitted by means of the pulleys F, F, and F Figs.22 and 23 show disks with a multiplicity of ribs 25 to t and jet-nozzlesG to C directed against the V-shaped ribs thereon. These disks are incontact along their side edges at p p and revolve at equal speeds.

In Figs. 2a and 25 the inclined sides of the V-shaped ribs may havepockets, as at r, the small V-shaped space being present as before, andin Figs. 26 and 27 two disks are shown with pockets in theirperipheries, this feature being old and well known, the only novelty inthis modification being that two wheels are used with their sideperipheries in contact at p p, so that they will revolve at equalspeeds.

In Fig. 28 a series of disks as 00 m are shown with a small space 3between them for the jet.

I claim-- 1. In combination the two wheels having their peripheriessubstantially in contact and grooved and ribbed, said ribs and groovesextending cireurnferentialiy around the two wheels and the fiuid jetpipe directed between the wheels to cause the motor fluid to strike theribbed and grooved surfaces, substantially as described.

2. In combination, the two wheels having their peripheries in contactalong their side edges and the intermediate portions of said peripherieshaving a space to receive the motor fluid and the jet pipe directed tosaid intermediate space, substantially as described.

3. A rotary motor comprisingapair of disks, one having a V shapedcircumferential rib and the other with aV shaped groove leaving a Vshaped passage between the disks, and the jet nozzle directed to themeeting points of the disks, substantially as described.

4. In combination, the two wheels having their peripheries grooved andribbed circumferentially and fitted to each other with buckets 7" formedin the periphery of one wheel, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
